Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
nhung cong » dung cong, thong cong, hang cong
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
ho chieu » hoc thieu, doi chieu, mot chieu
anh mang » anh bang, anh dang, anh nang
cong dan » cong san, cong tan, huong dan
dan van » dang van, doan van, dao van

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) sach - ((anh mang) OR (hanh mang)) cua nhung cong dan van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) sach - ((anh mang) OR (hanh mang)) cua nhung cong dan van ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) sach - ((anh mang) OR (hanh mang)) cua nhung cong dan van ban*.
